Solgar are good quality. I read that astaxanthin is good for eyes, cholesterol and all kinds of amazing things. I started taking it for my sight which seemed to be less clear in one eye. I have been taking these for a few months now and I think I have improvement. I had been taking vitabiotics for eyes daily, however, I think I have an improvement since taking these. my friend takes a higher dose together with other eye supplements as her sight was affected by diabetes and she has found supplements have improved her eye health. its worth trying, but down to personal experience. i'm not plugging these. just simply giving my own personal experience
